45MAN, it really opened up some new things for me. I'd been hunting with the same old 44 for years and really found out how much it had changed. It's put a new excitement back into it for me. I tend to listen to someone whom I feel writes from experience. Max's writing seems to be from someone who has been there and done that. His conclusions make sense to me, and he makes his case for the various calibers well. I think you will enjoy the book like I did.
